Exercise Triggers High Levels of a Hormones that Cause Cold
Researchers reveal that a hormone that is activated by exercise also activates a cold, according to a new study published in May 2018.
Researchers at Joslin Diabetes Center discovered a new kind of variable response to why everyone does not respond equally to exercise. They found that a hormone that increases in levels in the bloodstream by exercise is also increased due to cold.
“This is a whole new area in research on exercise metabolism, and we seem to have found another mechanism by which exercise can have beneficial effects,” said Laurie Goodyear, senior author of the report.
They conducted experiments on humans and mice, which proved increased levels of one lipokine, 12, 13-diHOME, due to exercise, unlike the levels of other lipokines analyzed.
“We found it very striking that when we then analyzed lipokines in exercise, the same lipokine that increased with cold also increased with exercise,” said Goodyear, a Professor at Medicine at Harvard Medical School.
The team measured levels of lipokines before exercise, immediately after exercise, and three hours after exercise in the blood of 27 healthy male volunteers of various ages. They found the high presence of the hormone.
They further studied lipokines in exercising mice and obtained similar results. “When mice do a single bout of exercise, we see an increase in 12, 13-diHOME. We also saw an increase after exercise training.” Goodyear said
